This product uses a new generation of Japanese ROHM's chip FM stereo radio
emission (BH1415F) Seiko-produced. This machine looks beautiful, with gold-plated
aluminum chassis fully closed, compact structure, shielding is good, solid firm, due to
BH1415F integrates PLL frequency PLL, audio pre-emphasis, limiter and low pass filter
circuit, the transmission frequency stability, quality class, a high degree of stereo
separation performance than the other forums using ROHM's predecessor (BA1404)
produced a more superior transmitter. Very suitable for the various tertiary institutions,
living quarters, towns and villages and the need to launch high-power high-fidelity audio
signals to suit the occasion.
The machine operation simple and easy wiring. Firing frequency of the front panel
display using LCD screen, step to 100Khz, through the bottom of the "+" and "-"
two touch switches to regulate the frequency of upward and downward, fast and intuitive.
"Audio" as the standard 3.5mm stereo input jack, you can easily connect to most home
stereo audio playback device. Back on the "DC12V" for 6.5mm power input socket,
through the external 12V/5A (optional larger current margin of) power adapter input
(jack inside the cathode), power adapter, switching power supply recommended , such
as notebook computers and LCD monitors and other external switching power adapter,
connector terminal with a magnetic ring filter is best, so can greatly reduce the power
of the transmitter interference, conditional use 12V power supply to the battery of the
transmitter .

Operation instructions
1. Operation steps: installing an antenna---->>> to connect the power ---->>>to
connect audio source---->>> to connect the microphone
2. Press the power button to boot into normal working condition.
AS the step of the bottom:
In the back of the transmitter, the antenna interface (ANT) as a BNC interface,
therefore, the antenna interface should also be as BNC. External power adapter output

voltage DC10 ~ 14V should be within the range of maximum output current should be
in 4A above. As shown, the power adapter DC plug connected to the transmitter back
"DC12V" on top of the power socket (Note the polarity is correct, he is outside the
negative)
As shown above, for connecting external sound source audio lines connected to
"AUDIO" interface. Should use more cable shielding performance audio cable, 3.5mm
plug.
Connect the microphone
Connected to the "MIC" jack. And audio cable, like a good selection of shielding
wires, plugs for 3.5mm. (Note: The microphone for the microphone type is Electret
condenser microphone.
Boot
After all the preparation work was ready, the power adapter open, the transmitter
is in standby mode the screen displays "OFF":
Click on the front panel
, The transmitter will enter the normal working state,
and then, through the "+" or "-" It's two buttons to adjust the working frequency of
the machine required frequency.

Special features of the setting and adjustment
1.Power Adjustment
The machine output power sub-two tranches: Power profile (H):> 5W;
low-power profile (L): <1W
First of all, turn off the power adapter (or disconnect DC12V), finished in the
transmitter power lines disconnected state, press and Hold
, And then connect the
power adapter (that is, DC12V connected to the transmitter), 3 seconds after release
the button, this time into the power to adjust the state, LCD display shows "L" or "H":
Click "+", set to high power (H), according to "-", set for low-power (L), select
the desired power profile, and then
, Power is set, it will go to set the frequency
range of the state.
2. Attention
(1)Before booting, be sure to had connect the antenna. It is strictly prohibited
empty boot.
(2) Audio cable must use shielded cable.
(3)The power adapter output DC voltage is selected as clean, so as not to interfere
with the transmitter.
(4) Avoid extreme hot or humid environment.
3. General troubleshooting.
A.The frequency can not be adjusted.
Reason: to set the frequency range may be errors, high-frequency than low-end
high frequency.
Solution: re-setting the relevant parameters (see instructions)
B. To open the boot method, press the power button, the flash look, LCD displays
"OFF"
Reasons: low-voltage, over-power adapter with a lower load capacity.

Solution: replace the power adapter (12V/1A)
C. Sound distortion serious
Cause: The input audio amplitude is too large.
Workaround: down the volume of the sound source.
D. Launch proximity
Reason: There may be power set to low power file (L)
Solution: re-setting power parameters.
